Clear or Re-Initialize A Graph

[ObeJuan]

I have XY-graph data that I freeze, now when I reinitialize the data/clear by zeroing an array, the display draws a line back to the begining of the graph and starts displaying new data. Question: How can I get not display the line drawing back? I have seen the Charts.llb examples where a property node.history, but I can not find it on the XY-graph property node. What am I doing wrong?

what you would want to do is create a property node from the graph and set it to reinitialize to default or clear graph. when i get back to my computer that has labview i will give you an example.

Could you explain how you "zero" an array? How many plots are on the graph?

You need to initilize with an array of zero length. (If you have a constant size array history buffer, fill all unwanted points with NaN instead of zeroes.)

May be you could attach a sample VI to show what you're doing.

Here is an example.
